SECURING LAMPS TO LANTERNS.

Specification of Letters Patent No. 11,849, dated October 24, 1854.

To all whom it may concern Be it known that I, IVILLIAM PORTER, of

. Villiamsburg, in the county of Kings and State of New York, have invented a. new and useful Improvement in the Method of Attaching Lamps to Lanterns, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure 1 is a view from beneath of the base of the lantern or that part to which the lamp is attached. Fig. 2, is a view from above of the same. Fig. 3, a section through the lamp and lantern upon the line A, B, of Fig. 1 the upper part of the latter being shown in elevation.

Lamps have already been secured to the lantern which hold them by means of springs pendant from the base and caught into the body of the lantern, but in all such cases the arrangement has been such that any oil which escaped from the lamp was at liberty to run through the lantern and to drop upon the clothes or furniture. To remedy this evil is the. object of my present invention which consists in placing the springs which hold the two together entirely beneath the base of the lamp, and in combination therewith, in surroundingthe lamp with a flange or cup which shall effectually prevent any oil which may escape from the lamp, from dropping upon either dress or furniture.

To enable others skilled in the art to make and use my invention I will proceed to describe the method which I have adopted of carrying it out.

a is the base of the lamp, having a disk 1 on the top, with a rim 5 around it; these serve to receive the lamp C, as noted hereafter. Beneath the disk 1 is a cross tube 6,

containing an expansive spiral spring 0, be tween two latch bolts 2, 2, in the ends of the tube; each bolt having a beveled catch 3, 3, projecting outside of the base a, and being fitted with a finger piece 4, 4, the shanks of which move in slots in the tube 6, by which the bolts are moved toward the center of the lamp base, to remove the latter from the lantern. A6, flange formed by the bottom of the lamp proper, fits into a rim 5, this flanch 6, has a notch in each opposite edge, to pass down the edges of stops 7, 7, on the rim 5, so that a slight turn of the lamp C, in either direction, the fianch 6 passing under the stops 7, secures the lamp efi'ectually in place, an equally slight counter turn being all that is necessary to remove it again from the base, for cleaning or to be exchanged for a full lamp, when needed; in either case the annular space between the body of the lamp C, and the rim 5, serves as a receptacle to catch and retain any overflow from the lamp, and thereby prevent the oil from being spilled about, to the injury of furniture or apparel; cl is the base of the lantern, having inside of it a feather edged flange e, the lower part of which takes, and slides over the beveled ends of the latch bolts 2, 2, and the horizontal part takes the underside of each bolt as the lantern is put on, which holds the lantern securely, until the finger pieces 4, 4, are compressed toward each other, by which the lamp base and lamp are easily detached from the lantern.

I am aware that lanterns have been made in which the lamp is secured by a crooked expanding spring, pendant from the body of the lamp, but in such lamps there has been no means of preventing the spillage of the oil as before stated, I therefore do not claim any such device, but

What I do claim as my invention and desire to secure by Letters Patentis The above described lantern constructed substantially as described.
